Proxy protocol for configuration RUNTIME - IS_URL - " " is not available Error

[poulamidas]

I am calling a web service from SAP TM NWBC to send delivery proposals to ECC and the exception CX_AI_SYSTEM_FAULT is getting raised. Nothing is captured in SRT_MONI and nor do I see any log in SLG1. We have Point-to-Point connection between TM and ECC. I debugged further and saw that the error code is ABAP.PRX_PROTO_NOT_SUPPORTED and the error text is "Proxy protocol for configuration RUNTIME - IS_URL - " " is not available. Check Configuration: OutboundDeliveryBulkCreateRequest_Out".

What can be the reasons for this? How to solve it?

If you have multiple replication targets and using local integration scenarios in SOAMANAGER, setting one of the ports to the default is not the solution. If this is your setup and you are still receiving this error, check that the point-to-point commnication is active via table SSOAV_WS_ACTIVE.
